To all whom it may concern: 1

Be it known that I, HAPRY-C. WAYLAND, a citizen of the United States, residing in the city of New York,borough of Manhattan, county and State of New York, have invented new and useful Improvements in a Crmbined Throat and smoke Chamber for Fireplaces, of'which the following is a specification.

My invention has for its principal object to provide means whereby the products of combustion arlsing from a fire place may be simply and efficiently conducted up through a chimney and so constructed that a down draft exerted in the chimney'and smoke chamber will not cause the smoke or gases to be impelled into the room in which the fire place islocated.

A further ob ect of my nvention is to provide a complete unit which shall"er n body the several features comprising my invention in such fixed relation to each other as to prevent any error in lnstalhng the,

throat and smoke chamber in a chimney.

Those objects I accomplish by the means hereinafter described and illustrated in the practical embodiment of my invention.

In the drawings, in which similar 'char acters of reference indicate corresponding parts throughout the several views Figure 1 is a front elevationof' a combined throat and smoke chamber applied to a fireplace I embodying my invention, the smoke chamthe front or breast of the fireplace being partly broken away for that purpose. Fig. 2 is a vertical transverse section partly broken, away, taken on the line 22 of Fig. 1.. Fig. 3' is a horizontal section partly broken away, taken on the line 33 of Fig. 1.

As illustrated in the drawings, the lower portion 1 of the back of the fireplace preferably extends in a vertical line or wall with the upper portion 2 inclined forward to aid in deflecting the heat from the fire place into the room in which it is located. The side walls 3 of the fire place are preferably constructed so as to flare outwardly from the rear wall, as shown in Fig. 3. The up- Specification of Letters Patent.

Application filed May 21, 1914. Serial at, 839,968.

per part of the fire chamber comprising the rear walls and sidewalls terminates in a throat, having a front wall 4, and rear wall 5 said walls being" inclined toward each other, and side walls (iwhich are preferably constructed so as to incline inwardly toward each other, as is illustrated by dotted lines in Fig. 1, so as to make a contracted opening or connection between the fire chamber below said throat and a smoke chamber 7 above said throat into which the throat terminat es;

The smoke chamber is preferably constructed of a front wall 7, rear wall 8, and

side walls 9. Ihe front wall 7 at its junc-' tion with the front wall 4' of the throat, preferably curves forward and then up ward, as illustrated in Fig. 2. And I prefer to make said junction in the form of a shoulder 10. The rear wall 8 of'the smoke-cham-- her, at its junction with the rear wall 5 of the throat, extends backwardly from the throat and is preferably concaved or dished at the floor 11 ofthe smoke chamber. As illustrated in Fig. '2, the junction between the rear wall 5 of the throat and the floor 11 of the smoke chamber may be, and in most instances is preferably, made slightly lower than the junction between'the front wall 4 of the throat and the front wall 7 of the smoke chamber. In such a construction if a down draft be exerted in the chimney after or while the smoke'from the fire place has passed from the fire chamber up into the smoke chamber, the down draft instead of forcing the smoke back through the throat and into the room, will strike the curved floor 11 of the smoke chamber and be de fiected forward thereby, against the front wall 7 of the smoke chamber and upward into the chimney, as indicated by the arrows in Fig. 2. The side walls 9 of the smoke chamber where they meet the side walls 6 of the throat, are-also preferably curved laterally from their junction'with the side walls of the smoke chamber, as shown by the lower portion 12 of said walls and indicated by dotted lines in Fig. 1. Those portions of the side walls of the smoke chamber also tend to prevent the smoke from being blown back through the throat by a down draft in the chimney. Instead of so doing the smoke position on top of said walls the space bea may be controlled by a hand wheel or knob 16 extending laterally from the breast of the chimney, or it may be controlled by a rod extending forward in the well known form as commonly used.

A fire place having a throat and smoke chamber constructed in the manner illustrated and hereinbefore described, when in use, will readily permit the smoke and gases to pass upward through the throat into the smoke chamber and from the smoke chamber up through the chimney to the atmosphere. And even if a down draft be exerted in the chimney, the smoke and gases will not be thereby forced backward into the room, but

on the contrary they will be deflected by said draft laterally and then forced upwardly and out of the chimney.

The throat and smoke chamber may be constructed of metal concrete or other suitable material, and is preferably constructed independently of the back and side walls of the-fire place proper, and when placed in tween the throat and smoke chamber and the walls of the chimney and the wall of the buildingv may be filled in with a mixture of concrete 1? or other similar material. In

' that way the throat and smoke chamber may be furnished to a builder complete and may be readily set in position by labor less skilful than would be required to determine and construct the proper shape and proportions of said chamber.

What I claim as new and desire to secure by Letters Patent is:

l. A combined throat and smoke chamber for fireplaces, the throat having front and rear walls inclined toward each other from their base upward, the smoke chamber having 'afront wall oflset at its'lower portion forwardly from its juncture with the front wall of the throat, and then inclined upward and backward, a substantially vertical rear wall, and a concave deflecting surface between the rear wall and throat.

2. A combined throat and smoke chamber for fireplaces, the throat having front and rear walls inclined toward each other from their base upward, the smoke chamber having a front wall inclined forward from its juncture with the front wall of the throat and then upward and backward, a substantially vertical rear wall, a deflecting surface between the rear wall, and throat, andend Walls deflected laterally from their juncture with the throat and inclined'upward toward each other.

a 3. A combined throat and smoke chamber for fireplaces, the throat having front and rear walls inclined toward each otherfrom their bas'eupward and oppositely disposed side walls inclined toward each other, the

smoke chamber having a front wall inclined forwardly from its juncture with the front wall of the throat and then upward and backward, a substantially vertical rear wall, and a deflecting surface between the rear wall and said throat having its main portion arranged below the level ofthe juncture between the front wall of the smoke chamber andthroat. .Y HARRY C.
